The Arc Blast is our Go-To backpack with the features a long distance ultralight backpacker needs.
It is built from tough but ultralight Dyneema Composite Fabric. It has our patented
'Flexed Arc' frame to
keep your back cool and cushioned while also providing superior load transfer. A full wrap
interchangeable belt,
and an adjustable torso height are standard to dial in a perfect fit without the guesswork.

The variations of our Arc backpack below have the same frame system with
alternative features.
